Three problems you know too well

  1. You're paying tax on a sale you never made.

    A move between your own wallets gets booked as a sale. You're taxed on a gain you never made.

  2. Your entire financial history sits on someone else's server.

    Your addresses, xpubs, and every transaction live on someone else's server. All it takes is one data breach.

  3. Your books don't balance. You can't prove they do.

    A matching wallet total is not a ledger. Without double-entry, there is nothing to audit.

Clams was built for exactly this.

  • Data stays on your machine by default.
  • Recognizes transfers from real sales.
  • Balances derived from real double-entry accounting.

Infrastructure

Flexible by design

Choose how you work. Start simple, scale as you grow.

  • One install, two interfaces: CLI and Server
  • Run it on your machine or your own server. Your choice.
  • Start local, go self-hosted later: same engine, same data model
  • Team-ready: invites, role-based permissions, multi-client workspaces

Specialization

Bitcoin-native

Built for multisig and the complex transactions legacy tools choke on.

  • Reconcile multisig wallets automatically. No manual matching.
  • Account for channel opens, closes, and force-closes, not just payments.
  • Handle on-chain fees and change outputs without inflating gains.
  • Account for L-BTC and Liquid assets like USDt alongside your BTC
